Problems solved by technology
The current limited-slip differentials use electronically controlled multi-plate clutches to achieve locking, but the response speed is relatively slow, and some are realized by purely mechanical worm gears, and the cost is relatively high. When used as a central differential It is also not convenient to set the unequal distribution of the output torque of the front and rear wheels

The invention relates to a forward output cycloid differential mechanism. The forward output cycloid differential mechanism consists of a housing, a crankshaft A, a crankshaft B, a crankshaft gear A,a crankshaft gear B, one or more linkage gears, one or more A type swinging gears, an output wheel A, one or more B type swinging gears and an output wheel B, wherein rotation axis centers of the crankshaft A, the crankshaft B, the output wheel A, the output wheel B, the crankshaft gear A, the crankshaft gear B and the housing are coaxial; the housing comprises an inner teeth gear ring which is circumferentially fixed to the housing, and is meshed with each A type swinging gear, and pin shafts which are circumferentially fixed to the housing, and respectively penetrate through corresponding pin shaft holes in the B type swinging gears; the crankshaft A and the crankshaft gear A are circumferentially fixed; each stage of crank of the crankshaft A penetrates through the center shaft hole ofeach A type swinging gear; pin shafts are arranged on the output wheel A; and the pin shafts of the output wheel A penetrate through corresponding pin shaft holes in each of the A type swinging gears.
Description
technical field [0001] The invention relates to a differential gear, which belongs to the technical field of mechanical transmission components, in particular to a forward output cycloid differential gear which can be used in automobiles. Background technique [0002] The differential is a mechanical transmission component, which is mostly used to transmit the power output from the gearbox of the car to two or four driving wheels. Due to uneven road surface and vehicle turning, the tracks of the driving wheels are different. If you keep the same speed Rotation will increase the friction between the wheel and the road surface, increasing the driving resistance of the vehicle, so the differential needs to output speed to the wheels according to the different operating conditions of each driving wheel. The traditional differential is mostly helical gear or crown gear structure. [0003] Limited slip differential, the English name is Limited Slip Differential, referred to as LSD...
